UNITED STATES PATENT FFICE.

JAMES BOON FINCH, OF NEWARK, NEW JERSEY, ASSIGNOR OF ONE-HALF TO ANDREW ALBRIGHT, OF SAME PLACE.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 325,664, dated September 8, 1885.

Application filed May 2, 1885. (Model.)

To all whom it may concern:

Be it known that 1, JAMES Boon FINCH, a citizen of the United States, and a resident formerly of Bozeman, in Montana Territory,

but now of Newark, Essex eounty,in the State of New Jersey, have invented certain new and useful Improvements in Horseshoes with Ad- 3 ustable Callas, of which the following is aspeeification.

IO My invention consists in an improvement in horseshoes whereby the calks, whether dull or sharp, may be readily changed.

In places where there are sudden and violent changes of temperature it is desirable to r 5 be able to quickly and easily change the calks from dull to sharp, or the reverse, without the aid of a blacksmith.

In the drawings, Figure l is a perspective view of my improvement, showing in position a dull toe-calk and two sharp heel-calks.

2 is a view showing my improved shoe with its calks removed. Fig. 3 shows a sharp toecalk. Fig. ishows asharp heel-calk. Fig.

5 is a plan of same.

The shoe A is of the ordinary shape and size of a horseshoe, but is provided with a recess at the toe and one at each heel for reception of the ca-lks.

a shows the toe-call; recess, which is under 7 0 cut at each edge and under the stud c, as in dicated by dotted lines in Fig. 2. This reccss conforms to and is adapted to receive the toe-call: B or B. The toe-calk B or B is slipped into recess a, its beveled edges fitting 3 5 under the undercuts, and the prongs 0 0 of the calk are bent down against inner edge of the shoe, thus preventing the calk from slipping out of its recess froutwise. The stud c prevents its rearward slipping. \Vhen the calk thus inserted is to be removed for an other ealk, any one can straighten or break off the bent prongs o o and drive the calk frontwise out of the recess a.

e e is the heel-calk recess, undercut at the back and ends to correspond to and receive the heel-ealk O, which is beveled at o o to fit into recess 0, and has aprong, i, to pass through a hole, 5, dotted line, Fig. 2, in the back of recess 0. This prong '6 extends through the upstanding part of the shoe which is back of said recess, and is bent down with a blow of a hammer, which thus holds calk O in position. a: a: are depressions in which the end of a punch may be inserted to aid in driving out the calks after the prongs have been bout 5 5 up or straightened.

By my invention any one can insert, remove, or change a set of calks easily and quickly.

Having described my invention, claim is l. A horseshoe having an undercut recess, and an abutment having openings, a removable calk having beveled edges adapted to fit in said recess and provided with prongs, said prongs passing through said openings and their ends properly bent to secure the calk to the shoe, substantially as shown and described.

2. A horseshoe having undercut toe and heelrecesses, each recess provided with an 7c abutment having one or more openings, re movable toe and heel calks adapted to fit in said recesses and provided with one or more prongs, whereby the calks are secured to the shoe by having said prong orprongs properly bent into engagement with said shoe, substantially as specified.

3. A horseshoe having undercut heel recesses and perforated abutments, removable heel-ealks having beveled edges, and each pro- 8( vided with asecuri ng prong, said. calks adapted to fitin said recesses with their prongs passing through the perforations and in the abutments and properly bent to secure the calks to the shoe, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 26th day of March, 1885.
